The Mattress Size Guide: Dimensions & Measurements

Are you looking for a new memory foam mattress but overwhelmed with all of the different sizes? It’s normal to worry about buying the right bed size. After all, larger beds can cost you more money and sometimes they might not fit where you want them to. And there’s nothing worse than realizing the bed you bought is too small! While you can always call/text us at 888-970-3563 or email us at, here’s an easy mattress sizing guide you can use to determine the measurements of your new bed:

Twin Size Mattress

Twin sized beds are one of the smallest types of beds and are often used by children. Single adults can also use a twin sized mattress if there’s limited space in the room. This size of bed is also popular in college dorms.

Size: 38” x 75”

Twin Size Extra Long

Twin sized extra long beds have the same width as a normal twin size mattress but are 5 inches longer. Extra long beds are good options for adults or college students.

Size: 38” x 80”

Full Size

Full sized beds are considerably larger than twin and are best suited for one sleeper. Some couples may buy a full-sized bed thinking there’s enough room for two only to realize it feels a little cramped. In fact, many couples end up having to replace their full-sized mattress later on as it’s simply not large enough for two people. However, if you’re a single person, a full-sized mattress can be rather spacious and comfortable to sleep on.

Size: 53” x 75”

Queen Size

A queen mattress offers a large and comfortable space for a single person to sleep. It’s also considered to be the minimum size a couple should buy.

Size: 60” x 80”

King Size

King sized beds are one of the largest options available and are perfect for couples who want a spacious sleeping surface. Single adults can also buy king sized beds if they’re looking for a luxurious sleeping experience.

Size: 72” x 80”

Cal King

Cal King sized mattresses are like king sized beds. The only different is they’re slightly longer and not as wide.

Size 72” x 84”
